ViewPager相关

设置ViewPager不可以滑动翻页
public class NoScrollViewPager extends ViewPager {

	public NoScrollViewPager(Context context) {
		super(context);
	}

	public NoScrollViewPager(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	@Override
	public boolean onInterceptTouchEvent(MotionEvent ev)
	{
		return false;
	}
	
	@Override
	public boolean onTouchEvent(MotionEvent ev)
	{
		return false;
	}

}

修改ViewPager调用setCurrentItem时，滑屏的速度  
   
1、自定义一个Scroll类，用于控制ViewPager滑动速度  

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.view.animation.Interpolator;
import android.widget.Scroller;
import java.lang.reflect.Field;

public class FixedSpeedScroller extends Scroller {  
    private int mDuration = 0;// 滑动速度  
  
    public FixedSpeedScroller(Context context) {  
        super(context);  
    }  
  
    public FixedSpeedScroller(Context context, Interpolator interpolator) {  
        super(context, interpolator);  
    }  
  
    public FixedSpeedScroller(Context context, Interpolator interpolator, boolean flywheel) {  
        super(context, interpolator, flywheel);  
    }  
  
  
    @Override  
    public void startScroll(int startX, int startY, int dx, int dy, int duration) {  
        super.startScroll(startX, startY, dx, dy, mDuration);  
    }  
  
    @Override  
    public void startScroll(int startX, int startY, int dx, int dy) {  
        super.startScroll(startX, startY, dx, dy, mDuration);  
    }  
  
    /** 
     * 设置速度 
     * @param duration 
     */  
    public void setScrollDuration(int duration){  
        this.mDuration = duration;  
    }  
  
    public void initViewPagerScroll(ViewPager viewPager) { //(NoScrollViewPager viewPager)  
        try {  
            Field mScroller = ViewPager.class.getDeclaredField("mScroller");  
            mScroller.setAccessible(true);  
            mScroller.set(viewPager, this);  
        } catch(Exception e) {  
            e.printStackTrace();  
        }  
    }  
}  
  
  
2、在Activity中设置切换速度  
FixedSpeedScroller scroller = new FixedSpeedScroller(mContext);  
scroller.setScrollDuration(0);  
scroller.initViewPagerScroll(am_viewpager);  //am_viewpager为你的viewpager
